CHARLES \V. HUNT, OF VEST NEl V BRIGHTON, NEXY YORK.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 452,135, dated May 12,1891.

Application filed February 16, 1891. Serial No. 381,597. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES W. HUNT, a citizen of the United States,residing at Vest New Brighton, in the county of Richmond and State ofNew York, have invented an Improvement in Railway-Oar Trucks, of whichthe following is aspecification.

In railway-car trucks such as shown in my patent, N 0. 347,936, a singleaxle with a pair of Wheels upon it has been pivoted at thecentral partby a sleeve around the axle and a triangular frame hinged to the frameof the car. In this construction of car-trucks there is oftenconsiderable bending strain upon the king-bolt, especially so when thejournalboxes are connected by links to the frame.

My present invent-i011 is intended to relieve the king-bolt from lateralor bending strain; and it consists in an arm extending out from thesleeve and bearing against guides upon the frame, so that the strengthof the arm or bearer is availed of for maintaining the bearer andking-bolt in a vertical position and preventing'the bending-straincoming upon the king-bolt.

In the drawings, Figure l is a plan view representing the presentimprovement as applied to a pair of truck-wheels, and Fig. 2 is avertical section at the line 00 a: of Fig. 1.

The wheels B are upon the axle O, and there is a cross-bearer or sleeveEbetween the two wheels and over the axle, and the truck or frame A maybe of either wood or iron, and itmay be either between the wheels oroutside of the same, and any suitable connection may be provided betweenthe axle-boxes and the frame. The king-bolt 5 serves to connect thesleeve or bearer E to the car, and this king-bolt 51night pass into across-beam of the car itself 5 but I prefer to employ a triangular frameL, through which the kin g-bolt 5 passes, and the base of the triangularframe L is represented as connected by the crossshaft or hinges 4: tothe car or truck frame. An arm G extends out laterally from the sleeveor cross-bearer E, and such arm passes in between two supports 6 and 7.Thesesupports 0 and 7 may be directly one above the other, or they maybe one in front of the other. I have represented such supports 6 and 7as upon the triangular frame L, and

the arm G between such supports is free to be moved by and with thesleeve or bearer E, as such bearer E and the axle assume a more or lessinclined position to the center of the all circumstances the pair oftruck-wheels, 1

axle, and sleeve can swing upon the king-bolt 5 in either passing arounda curve or in travcling upon a straight track, and the arm G between thesupports 6 and 7 relieves the king-bolt of any strain tending to bendsuch king-bolt, because the arm G holds the bearer E in its properupright position, but at the same time allows for the turning of theparts upon the king-bolt.

In cases where springs are applied between the hanging links and theaxle-boxes, it is preferable to make use of the triangular frameL and toprovide the supports 6 and 7 for the arm G upon such frame, because theparts are held in their proper relative position at the same time that arising-and-falling motion of the car-body'or truck-frame upon thesprings is allowed for. The flanges of the car-wheels B are on theoutside, as shown, because with one pair of wheels and an axle swingingupon the king-bolt the outer flanges are found in practice the mostreliable for giving the proper horizontal movement or swing to the axlein entering and leaving curves in the track.

I claim as my invention 1. The combination, with the car wheels andaxle, of a bearer on the axle and between the wheels, a pivot connectingthe bearer with the car body or frame, and an arm extending out from thebearer, and supports against which the arm is permitted to movehorizontally and by which the bearer is retained in normal position,substantially as set forth.

2. The combination, with the car-frame and the pivoted frame, of an axleand pair of Wheels, a sleeve or bearer over the axle between the wheels,a king-bolt connecting the bearer and the frame, an arm extending outfrom the bearer, and supports upon the frame,

the arm, between which such arm is allowed a limited horizontal motion,substantially as Set forth.

Signed by me this 12th day of February, 1891.
